easily made of uniform sizes and shapes and' the different parts of themangerand other concrete work will be more securely united together,which results will be attained by the expenditure of a minimum amount oftime and labor; and it consists of the employment of certain forms andappliances constructed and used as hereafter described to accomplish theresults herein set forth.

In the accompanying drawings forming a part of this specication, Figurel is a perview of the latter.

spective of a series of cow stalls having a partially constructed mangerprovided with appliances, embodying my invention. Fig. 2 yis atransverse section running through the partially completed section ofthe manger, substantially on the line 2 2. Fig. 3l is an enlargedperspective of a portion of one of the appliances. Fig. 4c is anenlarged top view of another appliance. Fig 5 is a side Referring to thedrawings, A represents the'top-rail, B the stall posts and C thepartitions of a series of cow stalls. These parts comprising the stallsare set up on the ground and are connected together inthe usual manneras shown. `After being propiv erly lined up to make the row of stallsstand plumb and true, boards D and D are set up on opposite sides of theVlower ends of the posts B tomake a form or mold' for the manger curb E,which is made of Vconcrete placed while in a plastic state between theboards D and D.

The boards on both'sides are supported in position'by stakesxS -drivenin the ground, the stakes on the rear side being hidden from view by theboards in Fig. l. It is preferable that a space of several inches beleft A between the lower edges of the boards and the ground so that theplastic cement or con-A crete' will run out under the boards to someextent and spread on the gro-undfor a short distance so as to form anenlarged base for the curb, which is built rst as shown by Figs. l 2.IBesides making a broader base for the curb it will also make roughenedsloping surfaces which will adhere better to the concrete thereafteradded.

It is important that the boards D and D be spaced apart equal distanceson eachV side of the posts B so that the posts will stand directly inthe center of the curb and not be set to one side or the other. Tofacilitate this central spacing I use devices F which may be calledcurbVV gages, enlarged views of which are shown by Figs. 4 and 5. The

upper inner edges of the form boards D and D. fare placed against theouter faces of the downwardly projecting lugs or shoulders f and nailsor screws may be driven through the holes in the ends of the gages theboards in this position.

Laterally projecting lugs g spaced apart so as to embrace some of thestall posts B are formed on the central portions of the gages. Theselateral lugs being equal dis-l tances from the adjacent dependinglugs'or shoulders j", the boards D and D will jbe held a uniformdistance from each other and equal distances from the postsl B. Nocutting ofbracin strips, nor measuring or fitting as was. formerlyneeded will be required to get the' parts in their properplaces. It ispreferablel to have laterally projecting lugs on each side of the gagesland to have the lugs on the opposite sides set 'different distancesapart so the spaces be-V tween them willV correspond with the differentsizes of the material that may be used for the stall posts.

In Fig.v 1, the 'section of the stalls at the right-hand end of thedrawing (the fourth section from the left-hand end) shows the formboards D and D in place ready for the placing of the concrete for thecurb, while the first, second and third sections from the left-hand endshow the curb completed and the form boards removed. The rst section atthe left also shows themanger I lconnpleted; the second section showsthe manger` to hold partly completed, andthe third `section showsnothing donetothe manger exceptthe completion of the. curb E and theset` ting up of a'portion of VVthe 'manger fr-oml ger as 'shown by Fig.Tlls'f'lfimgemeli) I" Y also insures a better joint between the man-'iger and concrete floors which, though not shown, are usually builtadjoining the curby which nails or screws may be driven to hold theupper ends of the templets on the upper edge of the form board H. Thelower ends of the templets are preferably set Yin recesses or pockets Nformed in the adjacent edge of the curb E which is built first asplainly shown in Fig. 2.

Y One or more pairs ofthese bent metal bars or templets are thus placedaccording to the length of the section of the manger/to be built at thesame time. The plastic cement is placed in position until it is Vevenwith or a little above the upper edges of the templets Twhen it issmoothed oft' even withk their upper edges by means of Vastraight edge.The workman stands outside of the form board Hand draws the straightedge to him.

If the cement is soft and will not atfirst stand in its proper positionat the upper edge of the manger, theworkman can continue'to draw it uptoward him until Vit has stiffened sufficiently Vvto stand; or ifpreferred he can clamp Va thin board or sheet of metal upon the upperportions of the templets to hold the cement in position until it hasstiifened sufficiently to stand alone. When the cement has stienedsuiiiciently to stand, the templets arey removed and the small recessesor grooves formed bythe templets, as well as the recesses or pockets inthe curb, are filled with cement by means of a trowel or otherwise, andthe face of the man- Y ger is troweled smooth and made continuous, asmay be required.

It is essential that the upper edges 'of the bars T be Vbroadened'togive them suicient lateral strength and to cause lesswear on-thestraight edge which is lused to form kthe interior surface of themanger, also, to secure suliicient vertical Vstrength Vwithout eX-tending the dimensions of the bars downward to any considerable extent.The 1recesses Voccupied by the bars having to be filled it isadvantageous to have them as shallow as possible. A T shape with thehead on the upper side is ythe preferable form for the bars, but othershapes 4may be used having a laterally extended upper sur- Vlouter `endof the bars doesaWay-Nvith the vor.

and hold the lower ends of the bars or templets, it is advisable to nailor tack a strip K on the inner side of the form vboard D" as shown byFig. l. This strip will form a con i tinuous groove in the side ofthecurb adjacentV to the inner face of the manger fas; shown 1nCrossfsectionjby F 1g. 2,'and .Willi Y insure the placing of thelowerends ofthe templets in line with each other. It'will also 1 form a moresubstantial jointV between `the Y cement ofthe curb and the body of theVmanger.V Without this groove there would probably be a perpendicularVseam Vwith aYY feather edge oint between Vthe Vcurb and Vthe tionable.

Y This defect Vwill .be @maar ty flani'ngV f the groove in thesideof thecurbfbymeans of the strip K tackedo'n the? Vform board D. This willthicken .what Ywouldotherwisebe Y Vbody of the-manger .which would beVobjec- Y Y' a feather edge of the main'part of the man- 4 ger adjoininglthe previously {eonstructed V Y sideof the curb, and it VVwill make Vahorizon curb by extending it Vintofthe-groove .in the tal instead of avertical joint.

Fig. 1V shows a different' step in thecon-Y il 'Y struction of theVmanger in each of'thefstalls,V Y' y Y 10o'V u but in .actualV operationthe same step is usually continued ythrough afsectlon of four or morestalls at the Sametime: The .objectV of the drawing is to illustratethefdiiferent steps in the. minimtunfof-spaeeforithe drawing. After themanger is completedthesstall floor and other Vfloors adjoiningit maylbeVV added in'theusual manner, but these .operai- .j

tions are not shown inthe drawings;
